35. Let, z = a + ib

(x+i)22x2+ 1

x2+ i2+2xi2x2+ 1 [since, (a + b)2 = a2 + b2 + 2ab]

x2 1+2xi2x2+ 1 [since, i2 = –1]

x2 12x2+ 1 + i2x2x2+ 1

So, |z|2 = a2 + b2

(x2 1)2(2x2+ 1)2 + (2x)2(2x2+ 1)2

(x2)2+ 12 2.x2.1+ 4x2(2x2+ 1 )2 [since, (a + b)2 = a2 + b2 + 2ab]

x4+ 12x2+ 4x2(2x2+ 1)2

x4+ 2x2+ 1(2x2+ 1)2

(x2+ 1)2(2x2+ 1)2 [as, (a + b)2 = a2 + b2 + 2ab]

Hence proved.

33. 21x2 – 28x + 10 = 0

Comparing the given equation with ax2 + bx + c = 0

We have, a = 21, b = –28  andc = 10

Hence, discriminant of the equation is

b2 – 4ac = ( 28)2 – 4 * 21 * 10 = 784 – 840 =  –56

Therefore, the solution of the quadratic equation is

32. 27x2 – 10x + 1 = 0

Comparing the given equation with ax2 + bx + c = 0

We have, a = 27, b = –10  andc = 1

Hence, discriminant of the equation is

b2 – 4ac = ( 10)2 – 4 * 27 * 1 = 100 – 108 =  –8

Therefore, the solution of the quadratic equation is

31.

Multiplying the above equation by 2, we get

2x2 - 4x + 3 = 0

and Comparing with ax2 + bx + c = 0

We have, a = 2, b = –4 and c = 3

Hence, discriminant of the equation is

b2 – 4ac = (-4)2 – 4 * 2* 3 = 16 – 24 = –8

Therefore, the solution of the quadratic equation is

30. 

Multiplying the above equation by 3, we get

9x2 + 12x + 20 = 0

and Comparing with ax2 + bx + c = 0

We have, a =9, b = –12 and c = 20

Hence, discriminant of the equation is

b2 – 4ac = (–12)2 – 4 * 9* 20 = 144 – 720 = –576

Therefore, the solution of the quadratic equation is
